Distribution and habitat
The fulvous-breasted flatbill has a disjunct distribution. In Venezuela it is known only from extreme southwestern Táchira with apparently no extension into adjacent Colombia. Other populations are found intermittently along the northern part of Colombia's Central Andes and on the western slope of the Eastern Andes. Another population is along Colombia's Western Andes from Antioquia Department south into northwestern Ecuador as far as Pichincha Province. The last is found from Sucumbíos Province in far northern Ecuador south along the eastern slope of the Andes through Peru and into northwestern Bolivia as far as Cochabamba Department.[4][5][6][7][8]Template:Excessive citations inline
The fulvous-breasted flatbill inhabits the interior and edges of humid to wet foothill and montane forests and secondary forest in the foothill and subtropical zones. It often is found near streams. In Venezuela it is found at about Script error: No such module "convert". of elevation. It ranges between Script error: No such module "convert". in Colombia, between Script error: No such module "convert". in Ecuador, and between Script error: No such module "convert". in Peru.[4][5][6][7][8]Template:Excessive citations inline
Behavior
Movement
The fulvous-breasted flatbill is a year-round resident.[4]
Feeding
The fulvous-breasted flatbill feeds on a variety of arthropods. It typically forages singly but often joins mixed-species feeding flocks. It tends to be sluggish, peering around and up from a perch in the understory. It captures prey in the understory to mid-story between about Script error: No such module "convert". of the ground, using upward sallies to snatch or hover-glean it from leaves and twigs. It only rarely takes prey in mid-air. It typically lands on a different perch after a sally.[4][5][6][7]Template:Excessive citations inline
Breeding
The fulvous-breasted flatbill's breeding season has not been defined but includes May in northern Colombia and August in Peru. Its nest is a large pear-shaped mass with a tunnel entrance that slopes up to near the bottom of the nest. It is made from rootlets, plant fibers, and dead leaves. It is suspended from the tip of a twig or a vine, typically over an open space or a small watercourse. The clutch is one to three eggs that are white with small reddish or cinnamon specks. The incubation period is about 24 days and fledging occurs at least 29 days after hatch. The details of parental care are not known.[4]
Vocalization
The fulvous-breasted flatbill's call is "an infrequent wheezy and upslurred 'zhreeyp' "[7] or "a rising, scratchy zreeee'zi'zi'zip"[8].
Status
The IUCN has assessed the fulvous-breasted flatbill as being of Least Concern. It has a large range; its population size is not known and is believed to be decreasing. No immediate threats have been identified.[9] It is considered rare in Venezuela and uncommon from Colombia to Bolivia.[4][5] It occurs in at least one protected area in each of Colombia and Ecuador.[4]
